Between January 1988 and January 1994, 24 patients with heterologous vascular bypasses were examined with suspected diagnosis of a perigraft reaction (PGR). All patients were subjected to ultrasound and CT. PGR ist defined as a sterile inflammation along the course of a vascular prosthesis. The typical clinical presentation is a fluctuating tumour with a localised painless swelling. In all cases liquid formations could be confirmed by diagnostic imaging procedures; signs of infection could be excluded. The synopsis of the clinical presentation, the time interval after implantation of the prosthetic material and the signs of sonography and CT can reliably exclude infection of the prosthesis and confirm the diagnosis of a PGR.
1988年1月至1994年1月期间，对24例进行了异种血管搭桥术的患者进行了检查，怀疑诊断为移植周围反应（PGR）。所有患者均接受了超声和CT检查。PGR定义为沿血管假体行程的无菌性炎症。典型的临床表现是一个波动性肿块，伴有局部无痛性肿胀。在所有病例中，通过诊断性成像检查均可确认有液体形成；可排除感染迹象。临床表现、假体材料植入后的时间间隔以及超声和CT表现的综合分析能够可靠地排除假体感染，并确诊PGR。
